Use of Ctrl+Alt+Del during log in
Hi there ,
It seems you need to know more info related to the sequential keyboard key ctrl + alt + del .
It is been noted as the SAK key or Secure Attention Key . It is been introduced into the Windows Platform from Microsoft corp.
Pressing this will validate that the user itself is logging in and not a computer program or an autobot is using your PC .
Windows has directly linked to the keyboard via their advanced keyboard drivers and hence direct inputs are stroked and recorded .
When they found the stroke ctrl + alt + del the SAK function is called and related operations are performed.
Hope that helped .
Good luck.

Hello Jovan.
Ctrl + Alt + Del (Control-Alt-Delete) is referred to as a secure attention key (SAK) or a combination of keys that are pressed before the operating system's kernel will trust the logon. The kernel interacts with the hardware directly and once it detects the SAK event, it can be sure that the login process can be trusted. Because of the above mechanism, a third-party program (such as a virus or trojan) will not be able to fool Windows into letting it intercept the log in password.
Ctrl-Alt-Del was chosen as the SAK for Windows NT and higher because nobody will think of redefining this key combination in the PC platform. Why? This is because it is recognized by the BIOS as a signal for a soft reboot. Notice also that if you are running DOS or Windows 3.11, Windows 95, Windows 98, Windows Me, pressing Ctrl-Alt-Del will result to a system soft reboot.
Hope this helps.

Using secure logon provides an additional layer of security for your by ensuring that the authentic Windows logon screen appears. When secure logon is enabled , no other program can intercept your user name password credentials as you enter them. To temporarily use the classic logon screen, press CTRL+ALT+DEL twice on the welcome logon screen. If you disable the welcome logon screen, you can also disable the fast user switching option.
